Questions and Answers

What is the main purpose of a nuclear reactor?

  • To create energy (correct)
  • To convert nuclear fuel into radioactive materials
  • To slow down neutrons
  • To protect people from radiation
  • What is the role of the control rods in a nuclear reactor?

  • To slow down the neutrons
  • To absorb neutrons (correct)
  • To protect people from radiation
  • To convert the mechanical work of the turbine into electrical energy
  • What is the purpose of the cooling water from the cooling tower in a nuclear reactor?

  • To extract the condensate from the condenser
  • To feed it back to the heat exchanger
  • To circulate into the condenser
  • To circulate the cooling water from the cooling tower to the condenser and heated water from the condenser back to the cooling tower (correct)
  • Study Notes

    • A nuclear reactor uses nuclear fuels to create energy.
    • The nuclear fuel is unstable and can be converted into radioactive materials.
    • In nuclear fission, the slow moving neutrons are bombarded on the atoms of the nuclear fuel.
    • The heavy nucleus of nuclear fuel like uranium is split into two or more lighter nuclei.
    • The reduced mass converted into enormous energy.
    • The energy released is taken away by primary coolant.
    • Parts of a nuclear reactor include the moderator, control rods, external shield, heat exchanger, generator, and condenser.
    • The moderator slows down the neutrons, the control rods absorb neutrons, and the external shield protects people from radiation.
    • The heat exchanger converts the heat from the nuclear reactor into steam, the generator converts the mechanical work of the turbine into electrical energy, and the condenser condenses the steam.
    • The feed pump extracts the condensate from the condenser and feeds it back to the heat exchanger, and the cooling water from the cooling tower circulates into the condenser.
    • The condenser water circulating pump circulates the cooling water from the cooling tower to the condenser and heated water from the condenser back to the cooling tower.
